While this new independent film distributed by A24 is set inside a prison in New York, it is less of a "prison movie" in the conventional sense and more of an emotionally impactful and inspiring drama about how art--particularly theater--can rehabilitate people in need of rehabilitation. The film's depiction of this issue is genuine and heartfelt, and forms the cornerstone to a generally engaging story. Colman Domingo plays the protagonist, who is incarcerated but helps lead the prison theatre group.
The film takes a bit of time to truly get going, but it still remains gripping and engaging. Domingo's performance is great, showing understated emotion in a way that makes a strong impact on the viewer, while also radiating a deep sense of compassion. The supporting actors are all excellent as well, and many of the supporting cast members apparently have been formerly incarcerated. The incorporation of the theatre program into the narrative creates comic relief, but also pathos and powerful bonding between the inmates and the program director. "Sing Sing" isn't perfect, as the character development of the supporting characters could have been improved, but its beating heart and thoughtful, humane tone is genuinely moving and memorable. Gladly recommended. 8/10.
